| Term | Definition |
| Premature Atrial Complex (PAC) | Individual Complex that occurs earlier than next expected complex. P waves- different in size, may be merged w/ T wave, or hidden under it. (T wave will look different than other) ***Depends ***Followed by a pause before rhythm returns |
| Bigeminy of PVC's | Every other QRS complex in a rhythm is a premature ventricular complex. (PVC) QRS-unifocal or mulifocal *Had delta little looking waves and every other QRS is flipped upside-down. |
| Sinus Brady | P waves- Upright (a little) before QRS complex PR- 0.12-0.20 QRS- less than .12 HR- slower than 60 P-P & R-R (same size) |
| Premature Junctional (PJC) | Occurs Earlier than expected followed by pause. Not a true rhythm P waves- inverted, hidden or retrograde ***PR-if seen, less than 0.12 QRS- less than 0.12 HR- P-P & R-R (Vary depending on rhythm) |
| Sinus Arrhythmia | P waves- Upright (a little) before QRS complex PR- 0.12-0.20 QRS- less than 0.12 HR- 60-100 ***P-P & R-R- IRREGULAR (Change with respirations) *Heart rate 6- second method is best to determine HR |
| Junctional Escape Rhythm | P waves- Retro, hidden, or upside PR- Vary QRS-less than 0.12 HR-40 ****Looks like a Normal Sinus Rhythm except for a "Premature" beat is seen. But Sinus has no Premature beats so its either atrial or junctional depending on p wave shape. |
| Wandering Atrial Pacemaker | Originates from at least 3 different sites above the bundle of his, involves any pace maker. P waves- lets you know location. PR- usually 0.12-0.20, varies by location of pace maker. QRS- vary HR-60-100 P-P & R-R (vary) |
| Supra ventricular Tachycardia (SVT) | P waves- normal before QRS, may be hidden under T wave PR- 0.12-0.20 QRS- less than 0.12 HR- 151-250 or more P-P & R-R (same size) |
| Atrial Flutter | P waves- None. **F waves instead **Saw-Toothed F to QRS- 2:1 ration, etc.. **QRS- not present for every F wave, less than 0.12 if any (regular) HR- 60-100<-- measured by QRS AR-250-350<-- measured by F waves R-R (Vary) <--6 sec strip |
| 3rd Degree Heart Block | When atria and ventricles both work independently as pace makers. **P waves- shows they change length but they do not really. PR- No true PR occurs **QRS- Wide, longer than 0.12 HR- 20-40 AH- 60-100 P-P & R-R (look equal, but not to each other.) |
| Torsades de Pointes | Looks Similar to Ventricular Tachycardia "WW", but has no pattern, is very random, and sides get smaller. P waves- Rarely seen PR- Not measurable QRS- Wide, Bizarre, longer than 0.12 HR- more than 150 HR R-R (Regular or slightly irregular) |
| Normal Sinus | P waves- round (look same) PR- 0.12-0.20 QRS- less than 0.12 (look same) HR-60-100 P-P & R-R (same size) |
| Sinus Tachycardia | P waves- Upright (a little) before QRS complex, May be hidden if fast HR under T wave. PR- 0.12-0.20 QRS- less than 0.12 HR- 101-150 P-P & R-R (same size) |
| Bundle Branch Block (BBB) | Impulse takes detour. "Rabbit Ears"<-- look like a delta dent in QRS P waves- Vary PR-Vary **QRS- more than 0.12 (Wider) HR-Vary P-P & R-R (Vary on Rhythm) |
| Accelerated Idioventricular dysrhythmia (AIVR) | *looks alike a sharp p, and low Q with. Like a V, but other side is not as steep. P waves-not present PR- Not measurable QRS- gradually decreases in amplitude, greater than 0.12, wide HR- 41-100 P-P & R-R (irregular) |
| Ventricle Tachycardia | Look like "WWWWW" P waves- Not usually present PR- Not measurable QRS- Wide, Bizarre, longer than 0.12 HR- 101-250 R-R (Regular, slightly irregular) |
| ST Elevation | the S wave and T wave are higher then the p wave. has to be more than one small box above baseline. |
| Ventricle Fibrillation (V-Fib) | Chaotic Wavy line on monitor. (No pattern) P waves- Not present PR- Not Present QRS- Not Present HR- Not Measurable P-P & R-R (Not Present) |
| Atrial Fibrillation (A Fib) | P waves and PR- No true waves exist because of quivering QRS- less than 0.12 HR- 60-100 AH- 350-500 R-R (irregular and no pattern)<-- Give away |
| 2nd Degree Type I | Mobitz I, Wenckeback More P waves than QRS PR- BECOME LONGER IN RHYTHM until QRS is dropped PR **Greater than 0.20 QRS- less than 0.12 HR- Vary |
| 2nd Degree Type II | Mobitz II, Classic P waves- More p waves than QRS PR- Normal or a little longer (DOES NOT GET LONGER IN RHYTHM) QRS- is dropped suddenly, (Wide) HR- Varies P-P & R-R (Regular until QRS dropped) |
| Asystole | Complete Lack of Electrical Activity in Heart. (No Pulse) Appears as a slightly wavy or straight linen screen. P waves- None PR- None QRS- None HR- P-P & R-R (None) |
| Paced Atrial Rhythm | P waves-Spike is seen at beginning of P wave. You can see a line where the artificial pacer started the impulse. |
| Premature Ventricular Complex (PVC) | Followed by a compository pause. You can measure by measuring R-R before and after PVC. Distance will be 2x more P waves- No P Wave when happening **QRS- Wide, bizarre looking, greater than 0.12 (Some appear Upside down) HR-Vary P-P & R-R (Vary) |
| Paced Ventricle Rhythm | P waves- Spike QRS- usually greater than 0.12 looks downward P-P & R-R (regular) You can see the line where Artificial pacer started impulse. |
| Accelerated Junctional | P waves- inverted, hidden, or retorgrade *PR- if present less than 0.12 QRS-less than 0.12 HR- 61-100 P-P & R-R (Regular) |
| Normal Rhythm | Sinus Rhythm, SVT, Accelerated Junctional |
| Irregular Rhythm | Sinus Arrhythmia, PAC, A-Fib, PJC, 2nd Degree type I, 2nd Degree type II, 3rd Degree HB, PVC, Idioventricular, |
| PAC | **Normal Sinus Rhythm if not for that ONE irregular one w/ pause making it an irregular rhythm. |
| SVT | **Confused with Sinus Tachycardia. Only its 150-250 and not 100-150 **Originates from above the bundle of his **Triggered by irritability in atria |
| Life Threatening | 2nd Degree Type II, 3rd Degree HB, Ventricular Tachycardia, Ventricular Fibrillation, Asystole, |
| Junctional | Inverted P wave (Upside down P wave) Buried P wave (Under QRS) Retrograde P wave (After QRS, close to J point) |
